The 40000W laser cutting machine is a high-power laser equipment widely used for precision cutting of thick metal materials, such as sheet metal processing, aerospace, shipbuilding, automobile manufacturing and other industries. With the development of laser technology, it has shown significant advantages in improving processing efficiency and cutting accuracy. This article will analyze its technical principles and performance characteristics.
1、 Technical principles
40000W laser cutting machineThe basic working principle of using the high energy density of a laser beam to cut metal materials is to emit a high-power laser beam through a laser, transmit the beam through an optical fiber to the cutting head, and then focus the laser beam onto the metal surface through a focusing mirror to form a high-temperature area. Metal materials rapidly melt, evaporate, or burn under the action of high-temperature lasers, while being blown away by high-speed airflow, ultimately achieving precision cutting.
1. Laser source: Fiber laser source is usually used. Fiber laser adopts the principle of solid-state laser, using erbium-doped fiber as the laser gain medium, and using high-power laser to excite particles in the fiber to generate laser radiation. Through wavelength adjustment, power control and other technologies, high-power laser output suitable for cutting different materials can be obtained.
2. Fiber optic transmission: The laser beam is transmitted through a fiber optic cable to the cutting head. Fiber optic transmission has the advantages of low loss and high efficiency, and has a long transmission distance, making it suitable for high-power applications. During the process of fiber optic transmission, the quality and stability of the laser beam are ensured through integrated optical components such as fiber couplers and mirrors.
3. Cutting head and focusing system: The laser cutting head is equipped with an optical focusing mirror, which is used to focus the laser beam into small spots and project them onto the metal surface. High power laser beams can heat metals above their melting point and locally melt them. The cutting head is also equipped with gas nozzles, usually using nitrogen, oxygen, or air as auxiliary gases to assist in removing molten material from the cutting area and improve cutting quality.
4. Control system: The control system adopts numerical control technology, which can accurately control parameters such as laser power, cutting speed, focal length, etc. Through real-time feedback mechanism, the system can adjust the output power of the laser, maintain cutting stability, and ensure machining accuracy.
2、 Performance analysis
1. High power cutting capability: The biggest feature of the 40000W laser cutting machine is its ultra-high cutting power, which can process thicker metal materials. Compared with traditional laser cutting machines, it can easily cut thick metal sheets, especially when cutting difficult to machine materials such as stainless steel, aluminum alloys, and titanium alloys, demonstrating advantages.
2. High cutting speed: Due to its strong laser output capability, it can complete the cutting process in a shorter time, thereby improving production efficiency. For cutting thick sheets, the cutting speed is much higher than traditional cutting techniques. In addition, the high-speed movement and precise control of the cutting head also ensure cutting quality and efficiency.
3. Cutting quality: It can achieve high-precision cutting, with narrow cutting seams, small heat affected zones, and almost no burrs or deformations. During laser cutting, due to the concentration of heat in a small cutting area, the material is uniformly heated and the cutting surface is smooth and flat. For thin sheets, very high cutting accuracy can be achieved, even reaching the micrometer level.
4. Widely applicable: capable of handling various materials, such as stainless steel, carbon steel, aluminum alloy, copper and other metallic materials, as well as some non-metallic materials such as plastic, wood, etc. This makes it widely used in many industries, including aerospace, automotive manufacturing, electronics, energy, and more.
As a high-power and high-efficiency cutting device, the 40000W laser cutting machine has become an important equipment in the field of thick metal cutting due to its powerful cutting ability, precise control system, and high cutting quality. With the continuous development of technology, its performance will be further improved, and its application prospects in more industrial fields will be broad in the future.
